The following example demonstrates using the Progress event.

Visual Basic

' Be sure to import the namespace by putting "Imports Dart.PowerTCP.Zip"
' at the top of your class.

Private Sub Archive1_Progress(ByVal sender As Object, ByVal e As Dart.PowerTCP.Zip.ProgressEventArgs) Handles Archive1.Progress
    Try
        ' Set the progress bar and status when fires
        ' prgItem is the progress bar for an individual item and prgTotal is for all the items.
        Select Case (e.Status)

            Case Status.Unzipping
                ' Show item progress
                prgItem.Maximum = e.Item.Size
                prgItem.Value = e.processedItemBytes

                ' Show total progress
                prgTotal.Maximum = e.TotalBytes
                prgTotal.Value = e.ProcessedTotalBytes

                Debug.WriteLine("Unzipping " + e.Item.Name)
            Case Status.EndUnzip
                prgTotal.Value = prgTotal.Maximum
        End Select
    Catch

    End Try
End Sub
